just touch the shield of the aux input to the metal of the empeg case

Hugo, remember you are talking to a technical ignoramus here.

By "shield of the aux input" you must be talking about the outer (bare metal) portion of the coaxial lead where it plugs into the sled, right? Do I have to do this for both the left and the right channel inputs, or would just one be sufficient? Does it have to be done at the empeg end of the cable, or could I do it at the portable player end, where access is easier? (I'd have to unbend the bendy-tabs (technical term) and remove the sled to do it at the empeg end although making the actual electrical connection would be more difficult at the portable player end)
